Application filed March 20, i908. Serial No. 422,245;

ence being had thereinto the accompanying g drawing.

illy inventionlrelates to iinprovements in carroofs and has reference primarily to providing an improved metal root composed o a series ot' pla-tes or panels and interlocking the root-plates and which shall provide tieni ble joints adapted to yield tothe pull or i compression which may be exerted thereon by the plates when under strain and tov cxpansion and contraction due to changes in temperature.

The invention consists in the arrangements and combinations of the parts hereinafter particularly described and then pointed out .in the appended claims.

ln the accompanying drawings vin which like referencenumerals .indicate similar parts in the ditlerent. figures; Figure l is aperspective view illustrating an embodiment of 'my invention showing ay cap and roof-'plates interlocked; 2 is a cross-sectional View on the line 2 2 of Fig. 1; Fig. 3 is a longitudinal sectionalmiew on the line 3-3 of Fig. 2; Fig. l is a` cross-'sectional view of the ca'p showing in dotted lines the out-bend of the sides; and Fig. 5 is a similar view sho\ving' in dotted lines the iii-bend of the sides.

ln the drawing the reference numeral indicates the rootplates which are preterably ot' galvanized iron but may be otany suitable material. ltis of course to be understood that the plates may be of any desired length and Width. Each side of the plates provided with an upturned and re y versely bent. flap 11 forming a vertica pocket, the iiap beiirg cut away at the zaves as at 19 for a purpose to be hereinafter made plain, and at its outer end each plate is downwardly bent to form a skirt 13.

The cap is preferably of the saine material the root'platcs and is composed oan upper horizontal portion le oit' sutlicient Width to extend across or over the pockets of adfaeent panels or plates, and of down turned and inturned sides which are brought under the horizontal portions7 the sides being then reversely as at 16 to form pockets for the bent down as at and then bentl sides ot the flaps l1 and again bent reversely as at 1i' to torni vertical portions 1n the pockets of the plates 10. The inturned poraway at. their front ends and tions of the sides of the cap are suitably cutthe head 14 of the cap is extended into a skirt or curtain 18 which may be bent down to overlie the' skirts 13 of the adjacent, panels, and also'inay be provided with a. reinforce 19 to stillen or give greater rigidity thereto.

A hood Q0 ot malleable iron or other suitable metal is adapted to interlock with the cap and comprises a-pair of parallel sides l 2l connected at one end by a tie 22 and at its other or frontend by a yoke or connection/JB. The yoke lies in a plane sufliciently lower than that of the tie so that before the skirt. ot' the cap is bent down and when it occupies the position shovvn in dotted lines in Fig. l, the hood may be slipped over the skirt ot the cap which passes freely between the sides and the tie and yoke. The sides 21 are inwardly and reversely bentalter the hofid is assembled to Jform recesses l into which the sides of the head lst of the cap are `adapted to seat, the sides of the hood beingI pressed together as at 25 by a suitable tool or in any other preferred manner. In assembling the hood upon the cap the former is slid along` the skirt ot' the latter until the yoke contacts with the cut away ends otl the ilapsl'l, and the skirt et the cap is then bent down to place and the sides 21 are contracted at 25 as before described to lock the hood to the cap.

llach cap is interlocked plates and the parts are assembled by layinfr the plates adjacent each other and posithen slid along the plates to proper position. lThe hood is then slid upon the outwardly l projecting end formed by the skirt of the head of the cap until the yoke contacts with the tlaps l1 Which are cut atvay at l2 Sulliciently to slip into place so that when skirt 18 is turned down to place it will overlie l and abut against the "skirts 13 of the adjacent panels, so that when they are secured to the side of the ear in the usual or in ,any suitable manner they conta ct along their )entire length to form a tight joint to prevent ivater or other foreign matter from getting beneath the rootplates and thus enter the car. lt. also to be understood and is clearly obvious from Fig. 2 that the bends and pockets of the panels l place.

The cap being of flexible material'prorides a iexible joint-between the panels so as to ltake up any strain or movement in the panels eausedbyithe action'oj the car Withr out` buckling the panels or causing them to the panels and caps as shown in Fig. 2 to provide the clearance. necessary to allow having fiaps,

` skirts of the caps, and 4theinturned -inturned fracture at their jointswliic'h is the initial point of breakage in most metal roofs. This 1 function of the caps is clearly shown in the drawing's'by 'reference to Figs. 4 and Whenone ot' the plates is subjected' to 'strain inthe general direction away from a cap, .the latter yieldsso that the interconnected parts occupy the positions shown in dotted lines in Fig. 4, and when a plate is subjected to strain .in the Vopposite direction the cap yields so that the interconx'iected .partsl oc- Fig. o. y

The hoods interlock with the caps and also with theendsjof the flaps of the panels yat or near the eaves, where the sides of 4the hoods ,also `close the openings between theV sides lofct-lle caps and the flaps formed by braces forl the curtains or P01" tions 25 ot' their sides are `located a suitable distaneeirom the interlocking portions of these parts to move whenl before described. Having described my invention,:I claim rl. I car-roof, a series ot" anels under strain as n a metal cap having inturned sides forming -channels to receive the'laps of adjacent panelslto interlock the cap With the portions of the cap being eut away head beingexat their iront endsand the skirts on the panels, a legible panels, and the i l i i I l I I l l l i l l j l y ,the eut-avay port-ions of the latter. `The v heods-alsoform' l I i l l y adaptedto interlock the sides of thelhead ,lock with the sides a cross-tie and a yoke above l the cap and caps are'adpted l tended into a curtain of substantially the to telescope-so thatthe caps may be slid :to samewidth as the head lie the skirts of adjacent panels. j
